Full list of online casinos

There are thousands of gambling casino online sites and at least a couple of hundred casino affiliate websites that sift through them for you. 

We don’t want to toot our own horn, but it’s been proven time and time again that if you’re looking for complete information, unbiased data, and a huge database of online casinos, bonuses and games – SlotsCalendar is the place for you.

We are, first and foremost, an aggregator of the best online casinos, games and bonuses, so no matter what you’re looking for (that’s worth checking out), we have it.

We list all the best casino sites immediately after they’ve passed all our extensive checks (even incognito ones where we pretend to be solely players to get the full experience). And we do it daily. We have all established brands already listed, and add new ones constantly, if they are what you want and need.

We’re also constantly updating our offers (all bonuses are tested, claimed and used) and we even review them so you may understand how to claim them, how they work and even what to expect from the terms and conditions.

And last and not least, we do something that no other aggregator does. We pair everything for you. Sure, you’ll see games or bonuses paired with the best gambling sites, but we make sure to pair games with bonuses that 100% work on that particular game, at the best online casinos that have the game and allow you to enjoy it.

This way, not only do you have thousands and thousands of options for games, best online casinos and promotions, but you may find what you like and make it all work together to your advantage.

Our Casino Sites Review Process 

Whenever we review gambling sites online, we have in mind several criteria. For a casino to make it to our best casino websites list it must check all of these things.

• License and Regulation: Reviews typically verify that the online casino holds a valid license and is regulated by a reputable authority. We only list websites that are safe and properly licensed and regulated.

SlotsCalendar Advice: Make sure you check that the license works for your jurisdiction. If you’re a UK player then a UKGC license is a must, but US players will require a different license.

• Security and Fairness: Online casino reviews also assess the measures in place to protect player information and ensure fair gameplay. 

This means employing SSL encryption technology to protect your personal and financial data, as well as being constantly checked by independent testing companies.

• Game Selection: The number and variety of games offered by the online casino is also evaluated, and the more, the better. 

It’s important that you have a wide range of titles and options to try so that you are entertained and don’t get bored.

• Bonuses and Promotions: Our reviews also look at the types of bonuses and promotions offered and their terms and conditions.

For a site to qualify, it must at least have a generous welcome bonus, if not some no deposit bonuses, or even a lucrative VIP program.

• Payment Options: The availability and reliability of various payment methods for deposits and withdrawals are also important.

We expect all sites to allow deposits and withdrawals using debit cards and wire transfers, and consider it a plus if you may use e-wallets, prepaid cards, pay-by-phone options or cryptocurrency.

• User Experience: This includes factors such as the design of the best gambling sites, ease of navigation, mobile-friendliness (either instant-play or through a casino app) and 24/7 friendly and helpful customer support.

Our reviewers take these factors into consideration, and they combine them to give an overall rating of each casino, which helps our players make informed decisions when choosing where to play.

What Types of Casino Sites Online You’ll Find on SlotsCalendar

The best gambling sites can fit into many different categories, each one coming with something exciting for players. While all of them are inherently great choices, it’s up to you and your personal preferences and gambling style to decide which one is right for you.

Top Casino Sites with Low Deposit Requirements

While there are no deposit bonuses that you can claim, eventually to play you will need to deposit to have more fun. This is where the best online casinos split into two categories – regular and minimum deposit casinos. Minimum deposit casinos will allow you to enjoy your favourite games for as little as £5, £3 or even £1.

Fast Withdrawal Sites 

In general, it takes about 3 to 5 business days to withdraw your winnings, but a fast payout casino will get you your funds almost instantly or up to 24 hours.

SlotsCalendar Advice: The rapidness of the process varies depending on the payment method you choose and how fast the casino verifies your request. We recommend choosing e-wallets and going through verification as soon as you create your account so that the withdrawal takes almost no time at all.

Latest Launches on the Market

The entire online gambling world can be split into two kinds of online casino sites – new brands and established brands.

The established ones are those who have been around for 3+ years, have a large client base, have settled into their own and are already well-known and appreciated by customers.

New casino sites have just been launched, they are still in their infancy as it were, but they have a lot of enthusiasm. They are striving to become the best and gather as many players as possible which is why here is where you will find the very best promotions on the market, the newest games and all the latest modern technology and design trends.

Casino Sites Online with Large Game Portfolios 

Having a huge game selection is paramount for top rated casinos if they wish to offer all players the opportunity to enjoy themselves. This may exist in one of two ways – either they have all the most popular titles of a single game type, or they have all popular titles from all the game types.

These are all the main game types that a site could focus on, either individually or at once:

• Poker – a game that relies more on strategy than on luck, poker has multiple variants that one may play both by yourself vs the computer, with others or in tournaments.
• Roulette – invented by Pascal when he wanted to create a Perpetuum Mobile, the roulette game is seen by many people as a main symbol of gambling.
• Live dealer games – this type of game combines all the perks of online gambling with the socialization and unique sensations of playing at brick-and-mortar casinos.
• Blackjack – one of the most famous games as many have made a fortune by counting cards at blackjack (not technically illegal but frowned upon).
• Slots – the most beloved game worldwide, slots are easy, fun, can bring you unimaginable riches and there are tens of thousands of variants available.
• Bingo – an easy-to-understand game, bingo is no longer just for old people and is gaining popularity each day.
• Crash gambling – a new type of game, crash gambling is an interesting option that combines slots with cryptocurrency or the stock market.
• Lottery – 1 of the oldest forms of gambling that’s still relevant today and the one that’s legal in almost all countries, even those that don’t have a regulated market yet.
• Slingo – an exciting combination between bingo and slots that’s surprisingly entertaining.

Casinos Where You Can Deposit with Your Preferred Method

The best online casino sites should have, as we’ve explained before on this page, a wide variety of payment methods. 

While there are other classic options, such as debit cards (even credit cards for non-UK residents) and wire transfers, the ones you will see below are newer, better, faster and more convenient:

• Boku
• Pay by SMS
• Paysafecard
• Pay by phone
• Apple Pay
